EPA has issued Federal Register (FR) notices seeking public comment on a concept paper and other materials related to its Nanoscale Materials Stewardship Program.

The debate still hovers around the issue if nanomaterials are to be considered as a 'new' material under the TSCA. J.C. Davies said:

“The agency’s current practice is inadequate to deal with nanotechnology. It is essential that EPA move quickly to recognize the novel biological and ecological characteristics of nanoscale materials. It can do this only by using the ‘new uses’ provisions of TSCA, a subject not mentioned in the EPA’s inventory document. With the approach outlined by EPA and because of the weaknesses in the law, the agency is not even able to identify which substances are nanomaterials, much less determine whether they pose a hazard.”

EPA also issued papers for public comment on Nanoscale Materials Stewardship Program (NMSP)—in order to encourage industry to provide a voluntary scientific information about the risk management practices currently applied.
